Abstract: 364,618. Reinforced concrete hollow walls, floors, roofs, &c. RIDLEY, M. N., 82, Harold Terrace, Burley, Leeds. Aug. 25, 1930, No. 25299. [Class 20 (iv).] Relates to means for forming permanent centring for hollow concrete walls, floors, and roofs, and consists in a construction involving the use of metallic sheets with dovetail or undercut corrugations, placed together with their edges contacting to form a hollow body engaging with metal bars of H, I, or U-section by means of the flanges. The whole is covered with concrete without the use of temporary shuttering. As shown, applied to walls in Figs. 2 and 3, troughs are formed by bending corrugated metal sheets 1, Fig. 2, across the corrugations at positions such as 5, 4. Thereby inclined sides 6 are provided at the wall corners and lips 7 which abut to form a cavity 15 and engage between the flanges of the girder 8. The girder 8 is fixed into the ground or otherwise arranged vertically and may be supplemented by a second girder 9. A similar construction is shown in Fig. 9 applied to a curved roof. For floors, inverted troughs are formed by bending corrugated sheets 1, Fig. 5, and are laid on flat corrugated sheets 1<x>. Before laying, the upper sheet may be rendered with fine concrete. Vertical stirrups 30 may be placed as and where required. After completion, the lower sheeting may be rendered with concrete. The lower sheeting may be dispensed with.

Abstract: 748,155. Transferring designs. JOYNSON, C. S. Aug. 17, 1954 [Sept. 14, 1953], No. 25348/53. Class 100 (2). A method of applying ornamental decoration to textile materials, such as linen, cotton or silk, includes applying the ornamentation to a sheet of impervious material such as greaseproof paper, in the form of a paint of which the base is a thermosetting plastic material, applying the decorated face to the textile material while the plastic material is in an uncured condition, pressing the ornamented face on to the textile material, and curing or partially curing the plastic material thus transferred by the application of heat, as by a hot smoothing iron. The iron may be applied to the reverse side of the sheet, but it is preferably applied to the reverse side of the textile material after removal of the sheet. A fixative comprising a thinner or solvent, e.g. a hydrocarbon solvent for the plastic base, may be applied to the textile material before the greaseproof paper is applied thereto. The base of the paint may be a urea-formaldehyde, or an alkyd synthetic resin made by reacting glycerol and phthalic anhydride, such as that sold under the Registered Trade Mark " Glyptal," or melamine, or epoxy synthetic resin, or a combination of one or more such resins. The paint comprises a mixture of a hydrocarbon solvent, a relatively viscous resin solution with a hardener liquid of low viscosity, and a thermosetting synthetic lacquer preferably including a urea-formalde- Hyde resin or a Glyptal or melamine resin or both, e.g. 1 part of a hydrocarbon solvent for the lacquer, 2 parts of the resin solution and hardener, 6 parts of a thermosetting synthetic lacquer, 2 parts of a thermosetting clear lacquer, and “ part of a fabric dye.

[Class 40 (iv)] [Also in Groups XXXV and XL] An antenna system comprising a number of separate antennae each of which deals with a particular part of the range to be covered is coupled through amplifiers to a common circuit feeding a number of all-wave receivers. As shown in Fig. 3, the antennae are carried by a common support, those pertaining to adjacent ranges being as far apart as possible. The shorter wavelength ranges are dealt with by di-poles, the longer by T & L antennae 129, 128, the effective capacities of which are increased by connections to the supporting wires of adjacent antennae. The amplifiers for the high frequency ranges have band-pass transformers the windings of which are tuned by adjustment of individual cores of magnetite. A single antenna deals with the normal broadcast range and is coupled to separate amplifiers 93, 95, 97 dealing with different parts of the range over a circuit 51 to which are coupled attenuating circuits 53 tuned to the frequencies of powerful stations to prevent overloading of the amplifiers. The common circuit 45 is associated with resistances 117 across which the individual receivers are connected by a pyramidal arrangement of bifilar transformers. The fourth transformer 113 may be replaced as shown by a resistance 114. Specification 477,890 is referred to.

Title: Electrophoretic coating process and apparatus
IPC: C25D13/22
Filed: 1964-06-24
Abstract: The interior of a hollow article is coated electrophoretically by inerting an electrode within the article, moving the article e.g. by a conveyer through the coating bath, and passing D.C. between the immersed article and electrode.  Preferably the insulation resistance between the article and electrode is measured automatically as the article moves with the conveyer before introduction into the coating bath and if this value is too low a relay operates to stop the conveyer and operate visual and audible alarms.  More than one sequence of electrode installation and insulation test may be effected before the article is immersed in the bath, which typically contains a dispersion of a cathodically or anodically depositable synthetic resin-based paint.  Current connection is made to the article via a bus-bar which may be segmented and connected to opposite poles of the D.C. source or not connected to either pole to permit control of the coating process.  Typically the tank containing the coating material is earthed and connected to one pole of the D.C. source so that the exterior of the article, e.g. a car body, is coated at the same time as the interior.  Suitable electrodes for insertion within the article are formed by a conducting bar within a flexible apertured sleeve of insulating material or an apertured metal cover spaced from a conducting current lead by insulating spacers.
